Traffic monitoring of Android application source code

Source code introduction <br /> A small example found on the Internet, which can count the network traffic of each application and distinguish between mobile network and WIFI. Technical points: Use TrafficStats to record traffic changes. Use Service, BroadcastReceiver to monitor network status changes. Use sqlite to record the traffic data used by each application (only the traffic used after the application is installed can be counted, and the traffic used before cannot be counted).

Code snippet:

 @Override  
 protected   void onCreate(Bundle savedInstanceState) {
 super .onCreate(savedInstanceState);
        setContentView(R.layout.activity_main); 
  
        txtView = (TextView) findViewById(R.id.textView1); 
  
        Intent intent = new Intent(MainActivity. this , TrafficService. class );

        findViewById(R.id.button1).setOnClickListener( new OnClickListener() {
